IMPROVEMENT lN MODES 0F ATTACHING SCYTHES TO 'SNATHS.

Specification forming part of Letters Patent No. [8, I 19, datedSeptember 1, 1857.

To all whom it may concern:

Be it known that I, OLIVER CLARK, of Henrietta, in the county of Lorainand State of Ohio, have invented a. new and Improved Method of AttachingScythes to Snaths and I do hereby declare that the followingis a. fulland exact description thereof, reference being had to accompanyingdrawings and letters of reference thereon, in which Figure 1 is aperspective view of the heel of the snath with the scythe attached; Fig.2, a side view of the metallic block A, to which the scythe is fastened.Fig. 3 is a plan view of the same, showing the vertical slot 12 throughits center. F1 g. 4 shows the under side of the same with the curved andconcave recess a, in which the scythe is held. Fig. 5 is a longitudinalsection of the same, showing the stirrup c in its place and itsmovement. Fig. 6 is the stirrup c. Fig. 7 is the washer or collar f;Fig. 8, the nut g, and Fig. 9 the scythe-heel.

The nature of my invention consists in so constructing and arranging theseveral parts as that the'scytheis securelyfastened,is easily andquickly removed and replaced, and is per: fectly adjustable in regard tothe elevation and depression of the edge and the angle of the blade tothe snath-i. e., the edge may be raised or depressed within limits whichare ample for all practical purposes, as much or as little as may bedesired, and the point set in or out more or less, according to theconvenience or fancy of the operator. v

1 construct a block, A, of metal, to be attached to the wood of thesnath by any suitable means,and extendingbeyond it, with avertical slot,b, through its center, a concave recess, a, in itslower surface, whichis also slightly curved transversely, and the upper surface, 0, convex,the are being concentric with that of the recess below; also,astirrup-bolt, 6, Fig. 6, a collar,f, Fig. 7, and a screw-nut, g, Fig. 8.The stirrup-bolt is seen in its place at Fig. 5, its stem passingthrough the slot 1) in the block A, Figs. 2 and 3, the collar beingunder the nut and its concave surface fitting upon the upper surface ofthe block. The scythe-"shank d is curved longitudinally to make it fitthe transverse curve of the recess a in the block A, and may have atransverse convexity corresponding with the concavity of the recess.

Theoperation is thus: The scythe-shank, being placed in the recess andthrough the eye of the stirrup, is tightened by the screw, and the shankbeing longer than the recess, the angle of the blade to the snath isadjusted by passing it (the shank) a greater or less distance throughthe eye of the stirrup, and the edge raised or depressed by moving thecollar longitudinally upon its seat, thus correspondingly rolling theshank in the recess.

I do not claim the making of a scythe with a curved heel, as I claimedthat in a former patent.

What I claim as my invention, and desire to secure by Letters Patent,is-

The metallic block A, in combination with the stirrup-bolt e, collar f,and scythe-heel d, constructed and arranged in the manner and for thepurpose set forth.

OLIVER CLARK.
